CVE-2018-16264

Local Bluetooth control and disclosure via D-Bus policy

Published Jan 22, 2020 · Updated Aug 5, 2024

Improper authorization in Tizen BlueZ before 5.0 M1 allows local users to read sensitive data or partially control Bluetooth. The BlueZ system-bus policy permits unprivileged processes to invoke protected service methods instead of restricting them to authorized callers. A local process on Tizen, including Galaxy Gear firmware before build RE2, is required; the reported effects are Bluetooth control and disclosure.
